Abstract
espanolEl presente articulo contiene los resultados obtenidos en las mediciones de potencial Zeta de un material biovitroceramico de CaO-MgO-PjOg-SiOj utilizando agua desionizada como medio suspensor y los pares HCl-NaOH y CH3COOH-NH4OH como agentes modificadores de pH. Se presentan las curvas pZ-pH de los sistemas indicados. En el sistema HCl-NaOH el material presenta un punto de carga cero en el rango de pH de 1,6 a 1,7. En el sistema CH3COOH-NH4OH se observa una linea de carga cero a pH inferiores a 2,0 EnglishThe present paper deals with the result of Zeta potential obtained in a CaO-MgO-PjOg-SiOj bioglass-ceramic. Measurements have been carried out by using deionized water as suspension medium and the HCl-NaOH and CH3COOH-NH4OH systems as modifiers agents. The pZ-pH curves are shown for these acid-base systems. In the HCl-NaOH system this material depicts a zero charge point in the pH=1,6-1,7 range. In the CH3COOHNH4OH system a zero charge line has been observed for pH lower than 2,0.
